● Selection of 6 Cylinder Diesel Engine 750 kW at 900 rpm<br />
driving a Centrifugal Pump.<br />
The coupling is flywheel mounted<br />
Pump shaft diameter = dm<br />
P = 750 kW n = 900 rpm<br />
dm = 95 mm temp = 30°C<br />
Fp = 1.7 Fm = 1.5<br />
TNORM = (P/n) x 9549 Nm<br />
= (750/900) x 9549 Nm<br />
= 7.958 kNm<br />
TMAX = TNORM (Fp + Fm)<br />
= 7.958 (1.7 + 1.5)<br />
= 25.466 kNm<br />
● The application is considered light industrial <strong>and</strong> RB type<br />
coupling should be selected. Examination of RB catalogue<br />
shows RB 3.86 as:<br />
T Kmax = 27.4 kNm T KN = 9.159 kNm<br />
which satisfies the condition<br />
● T MAX < T Kmax (25.466 < 27.4) kNm<br />
● T NORM
